RAILROAD CLOSET-TANK.

Specification of Letters Patent.

Patented Feb. 3,1914.

Application led August 2, 1912. Serial No. 712,889.

To all whom it may concern:

Be it known that I, HARRISON TAYLOR Gnomi, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Railroad Closet-Tank, o-f which the following is a full, clear, and exact description.

My invention relates in general to closet tanks, and more particularly relates to portable tanks adapted to be positioned on railroad trains and other` vehicles.

An object of my invention is to provide a tank of the above-indicated character which may readily be cleansed and disinfected in sita, and which is easy of removal.

A further object o-f my invention is to provide a hopper which may readily be raised out of its normal position without interfering with the flush pipe connection.

A further object of my invention is to provide a rigid, permanent and telescoping connection between the hopper and the trap.

A still further object of my invention is to provide a trap for the above-indicated device which may readily be positioned without interfering with the disposition of the hopper on the tank.

A further object of my invention is to so position a storage tank as to utilize as much as possible of the space vertically between the normal seating height of a person above the closet licor to a position as far below the underframe as possible without interfcring with the trucks.

Titli the above and other objects in view as will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawlngs, and more particularly pointed out in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of which indicate corresponding parts in all the gures, and in which- Figure 1 is a vertical longitudinal sectional view taken through a preferred embodiment of my invention shown in position on a steel passenger car of conventional type. Fig. 2 is a horizontal sectional view taken through the hopper and showing the fiush pipe connections, said view taken on the line 2 2 of Fig. 1; Fig. 3 is a vertical transverse section taken through the upper end of the trap showing the positioning rods; and Fig. 4 is a perspective view showing a form of closure cap.

Referring to the embodiment of the invention herein illustrated, a tank 8 preferably having a lining 4 is disposed in a recess in the floor 5 and supported in position by supporting brackets 6, which, as shown, may be angle extensions from the center and side sills of the underframe, and positioning plates above the floor, so as to position the tank partly below and partly above the line of the floor and underframe, in order that the hopper positioned on top of the casing will be at the correct height from the iioor without the use of supporting standards, and, at the same time, affording economy in the utilization of the space.

1n order to withdraw the contents of the tank while in position, there is extended through the lower central portion thereof, an outlet 9 outlined by a sleeve 10 having a ange 11 aiiixed to the tank 8 by suitable means. The opening is closed by a valve' cap 14, into which is fitted a pipe 15 forming an outlet through the cap, which outlet is controlled by a valve 1G. Extending into the tank and to the upper end thereof, is a contracted nozzle 17, at the end of a steam pipe 12, by means of which steam is admitted to the tank through a valve 19 to flush the same. By opening the valve 19, steam is admitted into the tank through the nozzle 17 and is withdrawn through the pipe 15 and hose connection 20 by opening the valve 16. Adjacent the nozzle 17, the lower end of a vent pipe 21 extends into the tank, the upper end of which pipe is opened to the outside atmosphere, preferably above the roof of the car, said vent pipe being' controlled by a valve 22 disposed therein.

Rigidly and permanently aiiixed centrally of the upper side of the tank, is a substantially cylindrical nipple 23 having a flange 24 extending about the periphery thereof and adapted to rest upon the upper face of the tank 8. The lower end of the nipple 23 is encircled by a flanged collar 25 wit-hin the tank and bearing on the under face of the upper side thereof. Adapted to be positioned within the enlarged portion at the lower end of the nipple 23, is a U-trap detachably connected to the nipple 23 and guided into position by means of a pair of spaced-apart guide rods 27 extending upwardly from the bottom of the tank 4, and so positioned with reference to the internal diameter of the nipple 23 that by pressing the trap against the rods and forcing it upward, said trap will be positioned within the enlarged portion of the nipple. It is held in this position by means of a supporting pin, the upper end of which is pivoted to the lug 29 at the bottom of the crotch of the trap, the lower end of which pin is adapted to tit within a socket 30 in vertical alinement below the lug 29. By this construction, it is possible to insert the trap from beneath the tank through the outlet 9, without in any way interfering with the tank or its attachments.

The upper end ofthe nipple 23 is conical and has an upper rim 31 upon which is disposed a ring gasket 3Q. Adapted to telescope into the conical part of the nipple Q3 is a similarly shaped extension 33 having a rim 34 adapted to tit on top of the gasket 32, to form a water-tight oint with the nipple 23. The extension 33 is integral with the hopper 35, which hopper may be of any construction now in common use. lVhen the hopper is removed the upper end of the nipple 23 may be closed by a cap 13 shown in Fig. 4.

The hopper 35 is mounted on the front portion of the upper face of the tank 8 and is pivoted to the same at its front edge. This pivotal connection is formed by extending through the lower front edge of the hopper, a sleeve 36 mounted in journals 37 at opposite sides of the hopper, which journals are fastened to the tank by suitable means, as, for instance, bolts 38. Extending part way through the sleeve 36 is a flush pipe 39, which fiush pipe extends through the walls of the hopper, as shown more particularly in Fig. Q, and has branches 40 extending in opposite directions below the curved upper edge 41, to form a flush for the bowl 42, as is common in devices of this character.

In order to permit the pipe 39 to swing with the hopper, a swivel connection 43 is interposed in the pipe 39 on the outside of the sleeve 3G. It will be seen that by this construction, it is possible to swing the hopper on the sleeve 36, constituting a hinge for the same, into the position shown in dotted lines in Fig. 1, but this movement will in no way interfere with the flush pipe 39, due to its swivel connection 43. It will also be seen that a rigid, permanent and telescoping connection is made between the hopper and the tank through the nipple 23 and extension 33.

Having thus described my invention what I claim to be new and desire to protect by Letters Patent of the United States is:

1. In a closet tank, a tank, a hopper pivoted to the front upper edge of said tank, an extension from said hopper leading into said tank, a removable trap within said tank and in vertical alinement with said extension.
